I saw this post on the front of slickdeals.net today and immediately thought of you guys. Mobil is currently having a mail in rebate promotion. You can get a $12 mail-in rebate when purchasing 5 quarts of Mobil 1 oil. Limit is 2 rebates per household. Here is some more information. Although Walmart and Amazon are not on the list of participating stores, people have called and confirmed that Mobil will honor it from these sellers.

Depending on your location you may be able to save on tax by ordering from amazon. Also if you spend $40 at amazon you get free shipping. So might as well order ten quarts for $45.32 with free shipping and get $24 back in mail in rebates.

I have attached the mail in rebate form. Also you can go here once you've mailed in the rebate to check the status of your submission.
